There are several companies who provide cable and central panels for the residential market. All include the basic panel then you up-grade for the features the customer wants. This can range from $800.00 to $5,000 easy. The problem with that is ALL homes need to be able to accept and use today's and upcoming technologies, not just the big ones. A new company has developed a panel with a price range to fit any home and it includes many features that the home owner needs and wants.
I have designed and installed over a 1000 home networks and would be gald to help out. I can also supply you with information on that new company, HCS Technologies. I did some consulting for for them and truely think its the best system out there.
